Floribunda rose plant named ‘JACarque’

ABSTRACT

Floribunda rose plant having an apricot gold flower color; resistance to blackspot and rust; strong, sweet fragrance; blooming in clusters; and upright, compact plant habit.

Genus and species: Rosa hybrida.

Variety denomination: ‘JACarque’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of floribunda rose plant named ‘JACarque’ which was originated by me by crossing the variety ‘AROfres,’ (not patented), with the variety ‘HARroony’(Amber Queen), U.S. Plant Pat. No. 5,582.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having healthy, disease-resistant foliage; upright, rounded, compact plant habit; golden apricot flower color; and strong fragrance.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

-   -   1. Beautiful apricot gold flower color.     -   2. Resistant to blackspot and rust.     -   3. Strong, sweet fragrance.     -   4. Blooms in clusters.     -   5. Upright, compact plant habit.

Asexual reproduction of this new variety by budding, as performed at Wasco and Somis, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

COMPARISON WITH PARENTS

The subject variety differs from ‘AROfres’ in flower color in that ‘AROfres’ is light yellow over the entire petal surface while ‘JACarque’ is Yellow-Orange. ‘JACarque’ also differs from ‘AROfres’ in fragrance in that ‘AROfres’ is not fragrant. ‘JACarque’ differs from ‘HARroony’ in that ‘HARroony’ has no orange tones at all and ‘JACarque’ is also much less spreading than ‘HARroony’.

COMPARISON WITH SIMILAR VARIETY

The variety most similar to ‘JACarque’ is ‘HARroony’ which differs from ‘JACarque’ as noted above.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart (2001), except where ordinary dictionary significance of color is indicated.
